TNSVD – For all AAC, AAAC, 
ACSR, Copper, SC/AC & SC/GZ conductor.  Made from high impact, UV stable PVC rod.

Spiral Vibration Dampers were designed to reduce aeolian vibration in conductors, generated by the wind.

The gripping part of the SVD should be installed about 100–120mm away from other fittings.  One SVD at each end of a span is adequate unless spans exceed 245m, where it is recommended two are installed at each end.
